[PD] convolve two arrays into a third

[Tim]

Hi,

I am looking for a way to convolve two impulse responses stored in two 
array offline (i.e. not strictly real-time) with each other into a third 
array, to combine the effect of both into a single convolution operation 
in real-time.

For MaxMSP there is a great tool by the University of Hudderfield called 
the "Impulse Response Toolkit" as part of the HISSTools, which can do 
exactly that. I was wondering if there is a port to PD or something 
similar out there.

Thanks!
